The SUB 650 is intended for high-performance speaker systems. It features a powerful front-firing design with an explosive 12in long-throw woofer. The SUB 650 is placed in an entirely closed cabinet, freeing it of any port noise. SUB 650 gives you extremely precise and tightly controlled sound reproduction. It is ideal for the demanding audiophile or musical connoisseur who wants to recreate the dynamic feeling of a live concert or cinema visit.
